Characterization and genetic distance analysis of isolates of Peronosclerospora sorghi using AFLP fingerprinting.
Sorghum downy mildew, caused by the obligate oomycete Peronosclerospora sorghi, has been controlled through the use of resistant cultivars and seed treatment with metalaxyl. A recent outbreak in fields planted with treated seed revealed the presence of a metalaxyl-resistant variant. Here, PCR-based methods including amplification from RAPD primers and two systems of automated AFLP analysis have...
متن کاملSugary disease or Asian ergot of sorghum - Claviceps sorghi
Claviceps sorghi is a pathogen of Sorghum bicolor found only in India and Southeast Asia. The more widespread C. africana is predominant even in India; C. sorghi appears to be marginalized in its restricted range. A significant difference in invasiveness is the relative production of inoculum that spreads plant-to-plant. Claviceps sorghi produces few to no secondary conidia from macroconidia on...

Results revealed that seven (7.1 %) cattle had trypanosome infection, mainly due to Trypanosoma viv...
متن کاملContrasting occurrence of Chromobacterium violaceum in tropical drinking water springs of Uganda.
Occurrence of Chromobacterium violaceum in six protected drinking water springs in Uganda was investigated. C. violaceum showed a contrasting occurrence, which was independent of human impact as assessed by faecal pollution indicators. It was isolated from two springs (S1 and S2) that were located close to each other (3 km) but not in the rest. In S1 C. violaceum was continuously detected, in c...
